I can’t install the game.

Hello, I recently wanted to install Heroes 5, the installation started, 70 percent of the game was installed, and I wanted to remove a couple of unnecessary processes through Task Manager, and accidentally removed the process related to the game installation. Well, I thought I would try to reinstall it, and then an error occurred: http://radikal.ua/data/upload/fb1a9/04012/b80a493a43.jpg
What should I do, please advise, because I really want to play the game:( :( :
